Engadget - If you recall, Synaptics is looking to branch out from touchscreens and touchpads and break into a another kind of navigation device: keyboards. The company announced several months ago that it was working on the so-called ThinTouch keyboard, whose slim profile might make it an ideal fit for Ultrabooks and other lightweight laptops. Back when it was first announced, we got to play with small wooden tiles, each of which had a single key affixed to it.
